This is exactly what I needed - I have a sit-stand desk, and floor-standing mic stands are a right pain to use with it. I have a couple of minor niggles with it.
Where the aluminium tubes attach to the middle joint, they are a bit loose & wobbly, though this isn't noticeable in normal use. The tubes and joints themselves are very solid.
The internal springing mechanism seems to be designed to counterbalance very heavy mics as it's really quite excessive - if I undo the locking knobs, the whole thing springs upright quite violently. You end up having to push it quite hard to lower it, and then tighten the knobs a lot to keep it in place - if they are loose, it will move upwards. I guess the idea is that the springs take the load rather than the clutches, but it's too much for a regular size capacitor mic (around 250g). This makes it quite tricky to adjust. There is a screw with an alternative position that looks like it might allow for a different position for the spring, but I think it would only allow me to make it stronger rather than weaker, and I didn't want to risk a springy explosion by taking it apart!
The section of cable at the top end is longer than it needs to be for me, but I couldn't see how to pull through some of the slack; it's all very firmly attached in there.
